AMD's newest roadmap reveals a major shift in early 2010: the company will once again overhaul its socket architecture to make way for DDR3 support.

The new socket, dubbed G34, will also ship with two new second-generation 45nm processors. The first of these processors, 8-core Sao Paolo, is described as a "twin native-quadcore Shanghai processor" by one AMD engineer. Shanghai, expected to ship late this year, is AMD's first 45nm shrink of the ill-fated Barcelona processor.

Both of these new processors will feature four HyperTransport 3 interconnects, 12MB of L3 cache and 512KB L2 cache per core.

Intel's next-generation Nehalem chip, scheduled for launch late this year but already well leaked, is the first to feature tri-channel DDR3 memory support. AMD will up the ante in 2010, with registered and unregistered quad-channel DDR3 support. Current roadmaps claim standard support will include speeds from 800 to 1600 MHz.

AMD insiders would reveal very little about the G34 socket, other than its a derivative of the highly secretive G3 socket that was to replace Socket F (1207). As far as company documentation goes, G3 ceased to exist in March 2008, and has been replaced with the G34 program instead. The first of these sockets will be available for developers in early 2009.

We counted 1974 pin connects on the leaked G34 diagram -- 767 more pins than AMD's current LGA1207 socket. Given the additional interconnect pathways for DDR3 and the HyperTransport buses, a significant increase in the number of pins was to be expected.

The addition of a fourth HyperTransport link may prove to be one of the most interesting features of the Sao Paulo and Magny-Cours processors. In a full four-socket configuration, each physical processor will dedicate a HyperTransport link to each of the other sockets. This leaves one additional HyperTransport lane per processor, which AMD documentation claims will finally be used for its long-discussed Torrenza program.

The hype behind Torrenza largely disappeared after AMD's Barcelona launch sour, though the company has hinted before that Torrenza will make a perfect interconnect to GPUs or IBM Cell processors. This is exactly the type of setup roadmapped for the fastest public supercomputer in the world, IBM's Roadrunner.

quote: "In France, after the First World War, the teachers’ unions launched a systematic purge of textbooks, in order to promote internationalism and pacifism.

Books that depicted the courage and self-sacrifice of soldiers who had defended France against the German invaders were called “bellicose” books to be banished from the schools.

Textbook publishers caved in to the power of the teachers’ unions, rather than lose a large market for their books. History books were sharply revised to conform to internationalism and pacifism....

In Britain, Winston Churchill warned that a country “cannot avoid war by dilating upon its horrors.” In France, Marshal Philippe Petain, the victor at Verdun, warned in 1934 that teachers were trying to “raise our sons in ignorance of or in contempt of the fatherland.”

But they were voices drowned out by the pacifist and internationalist rhetoric of the 1920s and 1930s.

Did it matter? Does patriotism matter?

France, where pacifism and internationalism were strongest, became a classic example of how much it can matter....

During the First World War, France fought on against the German invaders for four long years, despite having more of its soldiers killed than all the American soldiers killed in all the wars in the history of the United States, put together.

But during the Second World War, France collapsed after just six weeks of fighting and surrendered to Nazi Germany. At the bitter moment of defeat the head of the French teachers’ union was told, “You are partially responsible for the defeat.”

Charles de Gaulle, Francois Mauriac, and other Frenchmen blamed a lack of national will or general moral decay, for the sudden and humiliating collapse of France in 1940.

At the outset of the invasion, both German and French generals assessed French military forces as more likely to gain victory, and virtually no one expected France to collapse like a house of cards — except Adolf Hitler, who had studied French society instead of French military forces.

Did patriotism matter? It mattered more than superior French tanks and planes. ..."
